Title pretty much sums it up - I need a recommendation on a PE in Southern NJ to do the foundations and loading to EIA 222-G for: * A pad for a ground-mounted, RX only, C band antenna system (fixed,
I will be on site with Matthew and Art doing a bit of work on the station itself, so anytime after 10:00 would work. Re the insulator: I used a grinder to split the metal loop end fitting, leaving a

Anyone know what size and grade the bolts are in the ROHN EP25343 3 Hole Equalizer Plate? (or the part number for the OEM kit) 73 Martin W2RWJ _______________________________________________ ________

Marv, I reached out to our PE and explained your situation. His reply was to suggest that you retain the services of a local PE (stating the obvious and CYA) He did mention that he was involved in a

N2MO is using Andrew FSJ4-50B from the operating positions to the patch bay and triplexers, We ordered the 403A triplexers with the 7/16 DIN option, with the patch bay being 7/16 DIN as well. 73 Mart
Ran this past one of the code enforcement guys in the county. Surprising response: "We make you buy a UL listed panel board and breakers - what makes you think you can build a grounding system that i
Ken, So far I have not experienced the conditions you ran into. If I did, I would drive the rod at an angle or bury it in a trench. I will reach out the gentleman I quoted and see what is position is
Ken, The AHJ said to drive them at a 45 degree angle. Failing that, he would allow them to be placed in a trench with th bentonite slurry with prior approval. Martin I will reach out the gentleman I

The C84025-1 Coaxial Dynamics load (2.5 kW CCS) at our club station uses Dow-Corning Xiameter PMX-200 silicon fluid. A gallon was less then $50.00. We would have went with Diala ZX-4 transformer oil,
Not overkill for 375 ft! Might be the cheapest db's you gained with the tower + antennas investment. Grant KZ1W Not overkill at all. The N2MO Station at InfoAge uses heliax and superflex at HF, with
Chris, My club station used 7/16 DIN and Heliax all the way to the underside of the operating desks, through the protectors and patch bay. For the baluns at the antenna, we have swapped connectors, o
